Thanks for this! With this in place on beta 5 on ARM, the Swift compiler doesn't seem to be happy:

Running directly also includes:

zsh: segmentation fault   -frontend -interpret  -Xllvm -aarch64-use-tbi -enable-objc-interop -sdk     

So I suppose is a Swift compiler bug

building quarantine.swift with swiftc and then executing the compiled binary does seem to work, so might be an interpreter-specific problem
